Study Notes
Introduction to the Respiratory System
- The respiratory system's key function is to supply oxygen to the blood and remove carbon dioxide.
- It maintains the balance of oxygen and carbon dioxide in the body.
- The main organs of the respiratory system are the nose, pharynx, larynx, trachea, bronchi, and lungs.
Combining Forms in Respiratory Terminology
- Pulmon/o, Pneum/o, Pneumon/o: These terms refer to the lungs.
- Pulmonology: The study of lung diseases.
- Pneumonia: An infection causing lung inflammation.
- Bronch/o, Bronchi/o: These terms refer to the bronchial tubes.
- Bronchoscopy: A visual examination of the bronchi.
- Bronchitis: Inflammation of the bronchi.
- Trache/o: Refers to the trachea (windpipe).
- Tracheotomy: Surgical opening into the trachea.
- Thorac/o: Refers to the chest.
- Thoracotomy: Surgical incision into the chest.
Prefixes in Respiratory Terminology
- Tachy-: Fast (e.g., tachypnea - rapid breathing).
- Brady-: Slow (e.g., bradypnea - slow breathing).
- Dys-: Difficult or painful (e.g., dyspnea - difficulty breathing).
- A- or An-: Absence of or without (e.g., apnea - temporary cessation of breathing).
Suffixes in Respiratory Terminology
- -pnea: Refers to breathing (e.g., eupnea - normal breathing).
- -oxia: Refers to oxygen (e.g., hypoxia - low oxygen levels).
- -thorax: Refers to the chest cavity (e.g., pneumothorax - air in the chest cavity).
- -itis: Refers to inflammation (e.g., rhinitis - inflammation of the nasal mucous membranes).
Common Respiratory Conditions
- Asthma: A chronic condition with airway inflammation and narrowing, causing wheezing and shortness of breath.
- Chronic Obstructive Pulmonary Disease (COPD): A progressive lung disease obstructing airflow.
- Emphysema: A form of COPD causing damage to the alveoli (air sacs) in the lungs.
- Pneumonia: An infection leading to the inflammation of the alveoli.
- Tuberculosis (TB): A bacterial infection affecting the lungs.
Respiratory System Diagnostic Procedures
- Spirometry: A test used to assess lung function and airflow by measuring the volume of air exhaled.
- Chest X-ray: An imaging technique to examine the lungs and chest cavity.
- Bronchoscopy: An endoscopic technique to visualize the inside of the airways.
- Pulse Oximetry: A non-invasive method to measure oxygen saturation in the blood.
Medical Terminology Related to Respiratory Disorders
- Bronchiectasis: Chronic dilation of the bronchi.
- Pleurodynia: Pain in the pleura (lining of the lungs).
- Hemoptysis: Coughing up blood.
- Orthopnea: Difficulty breathing while lying down.
- Pleuritis: Inflammation of the pleura.
Respiratory Treatments
- Inhalers: Devices used to deliver medication to the lungs for conditions like asthma and COPD.
- Nebulizer Therapy: Converts liquid medication into a mist for easier inhalation.
- Ventilation Support: Use of ventilators to assist or replace breathing.
Case Study: History of Present Illness
- Difficulty breathing (dyspnea), persistent cough, and occasional chest tightness for two months.
- Fatigue and shortness of breath, especially when climbing stairs or during physical exertion.
- Chronic productive cough, often producing thick yellow sputum
- Smoker (one pack per day for 20 years)
- Wheezing (whistling sounds during breathing) and tachypnea (rapid breathing) during episodes of shortness of breath.
Case Study: Physical Examination
- Respiratory Rate: 26 breaths per minute (tachypnea).
- Oxygen Saturation: 88% (hypoxia).
- Lung Auscultation: Wheezing and crackles heard in the lower lobes.
- Chest X-ray: Hyperinflated lungs with evidence of bronchiectasis and emphysema.
Case Study: Diagnostic Procedures
- Spirometry revealed reduced forced expiratory volume (FEV1), confirming COPD.
- Pulse Oximetry showed low blood oxygen levels.
- Sputum Culture tested negative for infections, ruling out pneumonia.
- Diagnosis of COPD with coexisting chronic bronchitis and emphysema.
Case Study: Treatment Plan
- Smoking Cessation program to help quit and reduce further lung damage.
- Bronchodilators: Prescribed to open airways and improve airflow.
- Inhaled Corticosteroids: To reduce inflammation in the airways.
- Oxygen Therapy: To increase oxygen levels and alleviate hypoxia (low blood oxygen).
- Pulmonary Rehabilitation: Physical therapy and breathing exercises to improve lung function and stamina.
